[0013] Please see Figure 1-2 This utility model provides a technical solution: an end support assembly for the upper roller of a plate rolling machine that cooperates with a turning frame. The support assembly is installed on the extension section of the end of the upper roller 1 and includes a positioning ring 2, a bearing 3, a limiting plate 4, a support ring 5, a sleeve 6, and a cover plate 7. The positioning ring 2 and the bearing 3 are both sleeved on the extension section of the end of the upper roller 1. The bearing 3 is located at the outer end of the positioning ring 2. The limiting plate 4 is set on the outer end face of the end of the upper roller 1 by bolts. The bearing 3 is limited between the limiting plate 4 and the positioning ring 2. The positioning ring 2 and the limiting plate 4 respectively press the inner ring 301 of the bearing 3 to ensure the stability of the inner ring 301 of the bearing 3. The outer edge of the positioning ring 2 away from the bearing 3 is provided with an annular boss 8 on the end face. A first inner annular boss 9 is provided on the inner side of the sleeve 6. The sleeve 6 is fitted onto the outer end of the bearing 3, and the outer end of the bearing 3 abuts against the first inner annular boss 9. One end of the support ring 5 is inserted into the sleeve 6 and abuts against the inner side of the bearing 3. A second inner annular boss 10 is provided on the inner wall of the support ring 5. The end face annular boss 8 of the positioning ring 2 is in movable contact with the side surface of the second inner annular boss 10. The end face annular boss 8 and the second inner annular boss 10 do not have any compressive force when not subjected to external force. Only when the sleeve 6 is inserted into or disengaged from the turning frame, the end face annular boss 8 and the second inner annular boss 10 are in contact. Only platform 10 has supporting force. A connecting plate 11 is provided at the end of the support ring 5 away from the bearing 3. The connecting plate 11 is fastened to the sleeve 6 by bolts. The first inner annular boss 9 and the support ring 5 respectively press the outer ring 302 of the bearing 3 to ensure that the outer ring 302 of the bearing 3 can rotate with the sleeve 6. The cover plate 7 is provided inside the end of the sleeve 6 away from the support ring 5. The cover plate 7 is fastened to the first inner annular boss 9 by bolts. The outer diameter of the outer end of the sleeve 6 gradually decreases from the end near the upper roller 1 to the end away from the upper roller 1 so that it will not get stuck when inserted with the flipping frame and can be smoothly inserted with the flipping frame.

[0014] Installation method and operating principle: First, place the support ring 5 onto the extension section at the end of the upper roller 1. Then, place the positioning ring 2 and bearing 3 onto the extension section at the end of the upper roller 1 in sequence. Next, fasten the limiting plate 4 to the end face of the upper roller 1 with bolts. At this time, the inner ring 301 of the bearing 3 is clamped between the limiting plate 4 and the positioning ring 2. Place the sleeve 6 on the outside of the bearing 3 until the outer ring 302 of the bearing 3 abuts against the first inner annular boss 9 of the sleeve 6. Then, fasten the connecting plate 11 of the support ring 5 to the sleeve 6 with bolts. At this time, the annular boss 8 on the end face of the positioning ring 2 is in contact with the side surface of the second inner annular boss 10. Finally, insert the cover plate 7 into the outer end of the sleeve 6 and install the cover plate 7 on the outer end surface of the first inner annular boss 9 with bolts to complete the installation. In use, the tilting frame is tilted upright, and the sleeve 6 is inserted into the support hole of the tilting frame. When the upper roller 1 rotates, it will drive the inner ring 301 of the bearing 3 to rotate. When the tilting frame flips and disengages, the sleeve 6 can directly disengage from the support hole of the tilting frame. This utility model has a reasonable structure. The inner ring 301 of the bearing 3 is limited by the positioning ring 2 and the limiting plate 4. The outer end of the bearing 3 is provided with a sleeve 6, and the outer ring 302 of the bearing 3 is clamped by the first inner annular boss 9 of the sleeve 6 and the support ring 5. The second inner annular boss 10 of the support ring 5 is limited by the end face annular boss 8 of the positioning ring 2. This ensures that when the sleeve 6 is inserted into or disengaged from the tilting frame, the bearing 3 will not experience axial force causing the inner and outer rings to shift or even separate, ensuring smooth rotation of the bearing 3 and thus greatly improving its service life.
